SPECIFICATION forming part of Letters Patent No. 276,010, dated April 17, 1883.

Application filed November 2, 188:2. (No model.)

To all whom it may concern:

Be it known that I, DAVID E. DUTROW, a citizen of theUnited States. residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in the Propulsion of Vessels; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in the propulsion of vessels of that kind in which two or more paddle-wheels are connected and operated together; and the object is to provide means for operating said paddle-wheels at the same timeor separately, and to prevent the currents of water from the preceding wheels interfering with the action of the following or adjacent wheels byinclined-surfaced deflectors.

The invention consists in providing or fitting a boat or vessel with two or more sets of paddle-wheels, operated by means of two or more sets of rocking chairs or seats connected together and to the crank-shafts upon which the paddle-wheels are secured.

It also consistsin arranging deflectors in the so rear of the front and each succeeding paddlewheel, by which deflectors the currents created by the preceding wheels are prevented from interfering with the action of the following wheels, thus permitt-ingthem to operatein solid 3 5 water.

It also consists in the construction and arrangement of certain parts and details of construction, as will be more fully described hereinafter, and specifically pointed out in the claims, reference being had tothe accompanying drawings and the letters of reference marked thereon.

Referring to the drawings, Figure 1 is a side view of a vessel with three pairs of paddle- 4 5 wheels and provided with the water-deflecting devices. Fig. 2 is a top view of the same, showing the adaptation of my devices to steam and sea-going vessels. Fig. 3 is a side view of the connecting-rods which connect the shafts 0 of the paddle-wheels together. Fig. 4. is a side view of a boat with devices for propelling the same by manual power. Fig. 5is a top or plan view of the same. Fig. 6 is a side view of a vessel provided with three sets of paddlewheels and the deflectors to a proper scale.

In the drawings, A designates a vessel in which are mounted two or more pairs of paddle-wheels, B, on the ends of the shafts F F F, which are provided with cranks (J. They are connected together by means of pitmen or connecting-rods D D, the latter of which is bent, as seen in Fig. 3, so as to allow of its vibrating motion under the shaft G of the engine E- Motion is imparted by means of the shaft H and pinion and gear wheel I and J.

This form of construction is given as an illustration of the application of my invention to steam or sea-going vessels, and is to be used in connection with the devices or deflectors hereinafter more specifically described for deflectin g the currents of water.

In Figs. 4 and 5 is shown a boat or vessel which is to be driven by manual power, and the application of such power is through the medium of rocking chairs or seats. The rockers L of these chairs are-pivoted to the bottom of the boat. The rocking-chairs K K are con neoted together by pitmen or rods W in, any suitable manner, and at any one point, and said rockers are connected by a pitman or rod, 0, (one or more,) to the driving-shaft N. The driving-shaft is provided with a pinion-wheel, P, which meshes with a gear-wheel, Q, on the paddle-wheel shaft R. The paddle-wheels are connected by means of the rods S S, so that when power is applied to the shaft It all of the paddle-wheels will be set in motion.

A fiy-wheel may be used to regulatethemotion and assist the occupants in starting the vessel, and then by a rocking or to-and-fro motion of the bodies of the occupants of the chairs the vessel will be propelled in an easy and enjoyable manner.

To prevent the currents of water created by the movement of the paddle-wheels from impeding or interfering with the rear wheels or next adjacent to the preceding wheels, I have devised certain appliances for cutting or deflecting said currents, which I will now proceed to describe.

ICO

In the drawings, T is a diamond-shaped compartment, secured to the side of the vessel in such a position that it will cut or divide the current created by the paddle-wheels in front of it, deflecting said current to and from the vessel and preventing it coming in contact with the paddlewheels next behind it. It being a well-known law of nature that water seeks its level, it will be readily understood that the currents created by the preceding wheel will at once resume its level after having passed the deflectors. The currents of water will thus not interfere with the next following wheels, but permit them to operate in solid water. The wheels are of course not'arranged in close proximity to each other, as shown in Figs. 1, 2, 4, and 5, but are placed some distance apart, as represented in Fig. 6.

V are projecting wings, secured by brackets to the sides of the vessel, and are designed to deflect the currents created by the forward wheel from the vessel, and thus prevent impeding the progress of the vessel. These wings may be of any shape or size, so as to prevent the currents of a preceding wheel interfering with the action of the next adjacent wheel.

U is the rudder, which is of ordinary construction.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. In a vessel, the combination of two or more sets of paddle-wheels with inclined surfaces, substantially as described, arranged in rear of the preceding wheels to deflect the currents of water created thereby and prevent them from interfering or impinging against the adjacent wheels, substantially as specified.

2. The combination of two or more paddlewheels with deflectors having their sides and bottom formed with inclined surfaces to deflect the currents of water created by the preceding wheels from interfering with or impinging against the adjacent wheels, substantially as set forth.

3. As a means for propelling vessels, rocking chairs or seats connected by pitmen W and by pitmen O to the shaft N and by rod S together, substantially as specified.

4. The combination of the rockers or chairs K, pivoted to the boat and together by pitmen W, with the pitman O, shaft N, piuions P and Q, paddle-shaft R, and rods S, all arranged substantially as shown and set forth.

In testimony whereof I affix mysignature in presence of two witnesses.

DAVID E. DUTROW.
